A mental health program was commenced in 1957 in an electric power company which has about 360 offices and 17, 000 employees scattered throughout Kyushu. During a period of 30 years from 1957 to 1986, a total of 949 mentally ill employees sought consultation regarding various mental health problems.
Following the initial interview, periodic follow-up study was made on them. The results showed that year-end prevalence rate increased with continuation of mental health work and the rate reached 0.73% in the recent 5 years.
At the end point of the study, 358 employees (37.7% of the subjects) were working in the company and 591 cases (62.3%) had retired. The number retiring before reaching retirement age was 228 cases (24.0%) and in particular, retirement due to death and retirement due to disease in the subjects were higher in rate than those of all employees of the company.
